storage temp.

2-8°C

Application

In addition to protein determination and quantification in solution, the QuantiPro™ BCA Assay Kit has other applications, including determination of protein covalently bound to agarose supports and protein adsorbed to multiwell plates. It has also been applied to the determination of functional groups such as sulfhydryl, N-hydroxysuccinimido carboxylate, aldehyde and hydrazide on a variety of solid supports.
The kit can be used to measure very dilute protein concentrations in very small sample volumes. Accurately measures protein concentrations from 0.5 to 30 μg/mL in tube assays and 1 to 20 μg/mL in 96- or 384-well plate assays.

Features and Benefits

  • Accurate across a broad range of protein concentrations
  • High sensitivity; linear response form 0.5 to 30 μg/ml of protein
  • Stable color complex
  • Reduced susceptibility to detergents

Principle

Based on the alkaline reduction of Cu2+ to Cu1+ by proteins, and the formation of a bicinchoninic acid:Cu1+ complex having an absorbance maximum at 562 nm.

Storage and Stability

Store Reagents QA, QB, and QC at room temperature. Reagents QA and QB can be mixed together without Reagent QC (4% Copper(II) Sulfate Pentahydrate Solution 12 mL) and stored in a closed container at room temperature for a week. If this kit is received or stored cold, a precipitate may form in Reagent QA or Reagent QB. To dissolve the precipitate, warm the solution slowly to room temperature while mixing. The solutions are now suitable for use.

Vaults are ribonucleoproteins (13 MDa) highly conserved among lower and higher eukaryotes. Their association produces a complex composed of three proteins named Major Vault Protein (MVP), vault (PolyADP-ribose) polymerase (VPARP) and Telomerase-associated protein (TEP1), plus a small untranslated RNA.

Preparing Cell Lysates

This page describes common challenges encountered when lysing cells and extracting proteins prior to Western blotting. Total protein concentration must be determined for these cell lysates. Variables affecting each of these steps are outlined below, as each could affect the sensitivity and reproducibility of the Western blot.

Universal Proteomics Standards – Validating the Future of Proteomics

The era of high-throughput proteomics has recently blossomed due in large part to advances in the methods by which proteins and proteomes are analyzed. Improved fractionation techniques, combined with advances in mass spectrometry, have decreased concerns of sample complexity, and directed more focus towards high-throughput techniques.

Sample Preparation & Gel Electrophoresis Troubleshooting

The possible causes and potential remedies for challenges encountered during preparation of samples for SDS-PAGE (sodium dodecyl sulfate polyacrylamide gel electrophoresis) and optimizing electrophoresis conditions.

Western Blot Analysis of Immunoprecipitation (IP-Western)

The possible causes and potential remedies for challenges encountered in the immunoprecipitation-Western blot technique, which consists of cell lysis, formation of the antibody-antigen (immune) complex, precipitation of the immune complexes, and analysis by Western blotting.
